EXPANSION-JOINT HOLDER.

Specification of Letters Patent.

Patented May 231, 11918.

Application filed November 1, 1916. Serial No. 128,968.

To all "whom it may concern:

Be itknown that I, WILLIAM F. Wre- BERG, a citizen of the United States,residing at Cheektowaga, in the county of Erie and State of New York,have invented a new and useful Expansion-Joint Holder, of which thefollowing is a specification.

My invention relates to improvements in expansion joint holders for usein building cement, concrete or similar roads, drives, walks and thelike, in which the wooden or other expansion joint is held in place andkept from warping or springing out of shape during the operation ofbuilding the road or driveway by means of an angle iron frameconstructed and operated in the manner hereinatter described.

The objects of my invention are to provide a simple method of placingexpansion joints in roads, driveways and the like; to place such jointsaccurately and to make such a joint follow a straight line in an easy,sure, Speedy and inexpensive manner and to reduce the time and cost ofroad building.

I obtain these objects by the mechanism illustrated in the accompanyingdrawing, in which:

Figure 1 is a plan of my improved expansion joint holder. Fig. 2 is aside elevation of the same and showing the outline of the expansionjoint in dotted lines. Fig. 3 is a section on line A-A. of Fig. 2. Fig.4 is an end view of Fig. 2 as shown by line B-B.- Fig. 5 and Fig. 6 areplan and elevation of a catch for holding the expansion joint in place.

1 and 2 are angle irons having vertical legs 23 and 24; and betweenwhich the expansion joint 27 is placed (Fig. 3) after the holder is inposition on a street.

In Fig. 2 the width of the avement is shown by arrows and the verticallegs 23 and 24 of the angle irons 1 and 2 are cut oil" as shown at 26,26 and is the 'space occupied by the curb. 25, 25 in Fig. 1 shows wherethe vertical leg 23 of angle iron 1 is cut ofi'. In Fig. 2 the expansionjoint is shown by dotted lines and, is straight on the bottom andresting on the foundation of a street above which concrete is to belaid. The top of the expansion joint 27 is shown as being crowned andthe grade of the pavement is to be made to conform to this top line. 6

18, 18 and 19, 19 are pegs fastened to the vertical legs 23 and 24 ofthe holder and expansion joint 27. 3 and 5 are slotted as shown by 9 and10 to allow the expansion joint 27 to assume the position shown by thedotted lines in Fig. 2. 4 and 6 are vertical portions of the angle irons3 and 5 and have holes 29 and 30 to form handles for carrying theholder. '12 is a catch having a lip 31 and pivoted to angle iron 3 byrivet 14. 13 is a similar catch having a lip 28 and pivoted to an leiron 5 by rivet 15. Catch 13 is shown in etail in Figs. 5 and 6.

When the expansion joint 27 is in the position shown by dotted lines inFig. 2, the catches 12 and 13 are moved over the ends of 27 as shown bythe dotted lines 16 and 17.

21 is a link pivoted in the eye bolt 22 and held across the center orhigh point of the expansion joint 27 bymeans of a small crank catch 20.The handle 32 of the crank catch 20 is turned to the position shown inFig. 3 to lock the link 21 and thus hold the expansion joint 27 fromrising when concrete is being laced around it.

When the holder and expansion joint are in position as shown in Fig. 2the concrete is leveled up even with the top of the angle irons 1 and 2,when the holder is removed and the concrete then leveled up even withthe top of the expansion joint 27 and the holder then placed in anadvanced position two or three rods away and the pavement operationcontinued. The expansion joint is preferably a board of wood and the oldmethod was to drive stakes along side of the board and then fill in withconcrete. This board was hard to hold in position while with the presentmethod it is a comparatively easy matter and the street is leveled upexactly the same its entire length.

What I claim is:

1. In an expansion joint holder the combination of two angle irons,having them vertical legs extending down, fastened together at theirends and spaced apart so that an expansion joint may be interposedbetween said vertical legs, means to keep said expansion joint in astationary position, means to keep said joint holder in a stationary andvertical position, means for resting the ends of said holder on thecurbs of a street and means to remove said holder and leave saidexpansion joint in its permanent osition.

2. expansion joint holder having two angle irons spaced andfastenedtogether at their ends to form a frame, handles at the ends ofsaid frame to move said holder, and means to hold an expansion joint insaid space in said frame in a stationary and u right position.

3. an expansion joint holder the combination of aframe composed of twoangle irons spaced to receive an expansion joint, means to fasten theparts of said frame together, handles at the ends of said frame and pegsattached to said frame to fasten sa1d device in stationary and uprightposition.

4;. An expansion joint holder consisting of a frame composed of twoangle irons fastened together and spaced to hold an expanslon joint,catches to maintain said jolnt in a stationary position, handles at theends of said an 1e iron frame and spikes attached to said rame, to beinserted in the road foundation to hold said frame and joint stationary.
